All Scale Tomographic Reconstruction Antwerp Toolbox ("ASTRA Toolbox")

-----------------------------------------------------------------------
The ASTRA Toolbox is a MATLAB toolbox of high-performance GPU primitives
for 2D and 3D tomography.
We support 2D parallel and fan beam geometries, and 3D parallel and cone beam.
All of them have highly flexible source/detector positioning.
A large number of 2D and 3D algorithms are available, including FBP, SIRT,
SART, CGLS.
The basic forward and backward projection operations are GPU-accelerated,
and directly callable from MATLAB to enable building new algorithms.
Documentation / samples:
-------------------------
See the matlab code samples in samples/ and on
http://code.google.com/p/astra-toolbox/ .
Installation instructions:
---------------------------
Windows, binary:
-----------------
Add the mex and tools subdirectories to your matlab path.
Linux, from source:
--------------------
Requirements: g++, boost, CUDA (driver+toolkit), matlab
cd build/linux
./configure --with-cuda=/usr/local/cuda \
--with-matlab=/usr/local/MATLAB/R2012a \
--prefix=/usr/local/astra
make
make install
Add /usr/local/astra/lib to your LD_LIBRARY_PATH.
Add /usr/local/astra/matlab and its subdirectories (tools, mex)
to your matlab path.
NB: Each matlab version only supports a specific range of g++ versions.
Despite this, if you have a newer g++ and if you get errors related to missing
GLIBCXX_3.4.xx symbols, it is often possible to work around this requirement
by deleting the version of libstdc++ supplied by matlab in
MATLAB_PATH/bin/glnx86 or MATLAB_PATH/bin/glnxa64 (at your own risk).
Windows, from source using Visual Studio 2008:
-----------------------------------------------
Requirements: Visual Studio 2008, boost, CUDA (driver+toolkit), matlab.
Note that a .zip with all required (and precompiled) boost files is
available from our website.
Set the environment variable MATLAB_ROOT to your matlab install location.
Open astra_vc08.sln in Visual Studio.
Select the appropriate solution configuration.
(typically Release_CUDA|win32 or Release_CUDA|x64)
Build the solution.
Install by copying AstraCuda32.dll or AstraCuda64.dll from bin/ and
all .mexw32 or .mexw64 files from bin/Release_CUDA or bin/Debug_CUDA
and the entire matlab/tools directory to a directory to be added to
your matlab path.
